OG Image Builder

What Is an OG Image Builder?

When someone shares a link on Facebook, LinkedIn, X, WhatsApp, or Slack, the platform renders a preview card. The large picture in that card is the Open Graph image, and its recommended size is 1200 by 630 pixels with a roughly 1.91 to 1 aspect ratio. This builder lets you compose that image visually: type a headline, add a supporting line, pick your brand colors, optionally upload a logo, and watch the canvas update as you type. When it looks right, download a ready to upload PNG with a single click.

Why Open Graph Images Matter

Shared links with a well designed preview image earn noticeably more clicks than plain text links. The image is often the first thing a reader notices, and it sets the tone for the page behind it. A default screenshot or a missing image makes a link look unfinished, while a clean card with a readable headline, your site name, and consistent brand colors signals that the content is polished and trustworthy.

How the Builder Works

Everything is drawn onto an HTML canvas element inside your browser. The canvas is a full 1200 by 630 pixels, exactly the size you will export, and the preview under the form is that same canvas scaled down to fit the screen. Nothing is uploaded to a server, so no design drafts, titles, or logos ever leave your device.

• Title: rendered in bold and automatically wrapped across up to three lines. If the headline is long, the font size steps down from 68 pixels until it fits.
• Description: a smaller supporting sentence or two, shown at reduced opacity so the hierarchy stays clear.
• Site name: a small accent colored label above the headline that anchors the card to your domain.
• Colors: separate pickers for the background, text, and accent, with the accent used for the tag, decorative circles, and the bottom strip.
• Logo: an optional image scaled proportionally to fit the bottom right corner, up to 220 by 90 pixels.

How to Use the OG Image Builder

1. Enter your Title and an optional Description. Shorter titles render largest and stay most readable in small preview cards.
2. Set the Site Name that appears above the headline.
3. Adjust the Background, Text, and Accent colors. Dark backgrounds with light text and a bright accent work well on every platform.
4. Optionally upload a Logo in PNG, SVG, or JPG format.
5. Click Download PNG and upload the file as your page's og:image.

Design Tips for Social Cards

Keep the headline under about eight words so it reads at thumbnail size. Leave breathing room around the edges, since some platforms quietly crop or overlay controls near the corners. Use high contrast between text and background, and avoid tiny details that disappear when the card is scaled down in a feed. Pair the image with a matching og:title and og:description, which you can generate with the Meta Tag Generator, then double check how the card will look with the social preview tool before publishing.
